Identifying a signal on a printed circuit board under test

Apparatus for identifying a signal on a printed circuit board (‘PCB’) under test, the PCB comprising a plurality of electronic test points, a plurality of the test points characterized by a conducting of test signals, the apparatus comprising:

• a test probe comprising a radio transmitter and transmitter antenna, the test probe positioned with the transmitter antenna at a test point on the PCB, the test probe transmitting a radio signal;
• at least two radio receivers, each receiver comprising a receiver antenna, each receiver antenna positioned at predetermined, separate physical locations with respect to the PCB, the receivers coupled to at least one signal strength meter, each receiver receiving the transmitted radio signal;
• and
• a signal-identifying controller comprising a module of automated computing machinery, the signal-identifying controller connected to the at least one signal strength meter and also connected to a display, the signal-identifying controller reading, from the at least one signal strength meter, signal strengths of the transmitted radio signal as received at the radio receivers;
• determining, in dependence upon the read signal strengths, a test signal identifier;
• and displaying the test signal identifier through the display, wherein the signal-identifying controller further comprises a list of signal strengths associated with test signal identifiers, and determining a test signal identifier further comprises looking up a test signal identifier in the list.

A computer program product for identifying a signal on a printed circuit board (‘PCB’) under test, the computer program product disposed upon a computer readable storage medium, the computer program product comprising computer program instructions capable, when executed, of causing an automated signal-identifying controller to function by:

• reading, from at least one signal strength meter, signal strengths of a transmitted radio signal as received from a test probe by at least two radio receivers, the test probe comprising a radio transmitter and transmitter antenna, the test probe positioned with the transmitter antenna at a test point on the PCB, each receiver comprising a receiver antenna, each receiver antenna positioned at predetermined, separate physical locations with respect to the PCB, the receivers coupled to the least one signal strength meter;
• determining, in dependence upon the read signal strengths, a test signal identifier, wherein the signal-identifying controller further comprises a list of signal strengths associated with test signal identifiers, and determining a test signal identifier further comprises looking up a test signal identifier in the list;
• and
• displaying the test signal identifier.
